Comments? I'm interested in the literature in arguments for
physical space having n dimensions. Any good reads you can
recommend in this area?<br>

I got my earliest introduction in Barrow and Tipler's "The Anthropic
Cosmological Principle". Max Tegmark has a few nice papers too.
Lämmerzahl and Macias try to prove it using the Dirac equation
instead:

Caruso instead argues that the formation of life puts in the
constraint, and points out that it looks unavoidable to get some
form of the anthropic principle to do the work in this kind of
argument: <a href="http://arxiv.org/abs/0806.0684v1">http://arxiv.org/abs/0806.0684v1</a><br>
<br>
Some other books are "Relativity and the Dimensionality of the
World" ed. Vesselin Petkov, Springer 2007, apparently a sequel to
the more philosophical "The Ontology of Spacetime".<br>
<br>
But as the initial paper shows, there are deeper problems in how one
can "prove" it than most papers discuss. I know philosophers of
physics wrestle with this quite a lot. <br>
